negspacy not working

[cangainuren]

I'm having problem running the following example. I have spacy 3.4 and latest negspacy.

import spacy
from negspacy.negation import Negex

nlp = spacy.load("en_core_web_sm")
nlp.add_pipe("negex", config={"ent_types":["PERSON","ORG"]})

ValueError: [E002] Can't find factory for 'negex' for language English (en). This usually happens when spaCy calls nlp.create_pipe with a custom component name that's not registered on the current language class. If you're using a Transformer, make sure to install 'spacy-transformers'. If you're using a custom component, make sure you've added the decorator @Language.component (for function components) or @Language.factory (for class components).

Your code works fine for me - can you confirm you have the latest version of negspaCy installed? Check the output of pip freeze.

Also, note that negspaCy is a third party project not developed by us, and it may be better to ask questions at their repo.
